Current asterisk SS7 implementations (both chan_ss7 and libSS7) only supports fully associated signaling that means signaling links must be in the same E1/T1 as bearer. No matter what type of link you are dealing with (usually A or F ones). The main limitation for this configuration is that you can not have multiple asterisk boxes attached to a pair of signaling links, your asterisk switch is the limitated to how many trunks you can install in a single box. channSS7 has made some great job allowing clusterization but still limits the possible configuration schemes. This configuration imposes a constrain specially when you connect with public switches, usually telcos uses non associated signaling and some sort of ISUP redundancy. Hope this helps.
